Specification of Letters Patent.

Patented. April 24., 1906.

Application filed January 3,1906. Serial No. 294.362.

To It wir /mu it m u con/w 22,:

Be it known that l. (.nAnL'ns J. (.Losn. u ditizen ot the llnited States, rcsuling at (olumbus, in the county of Franklin und State.

of ()hio, have invented certain ncw und uset'ul Improvements in Dumpingdiuckcts, of which the following is a specification.

My invention relates to dumping-buckets,

especiallyof the kind adapted to travel in u verticul shaft and tube automatically dumped at u predetermined point, and comprises improved bearing-surfaces for the bucket us it up and down the shaft, improved menus for causing the bucket to dump, and

means for preventingthc buckct l'rom tipping a verticul sectional view of :1 shaft with bucket in place therein.

and the bail by which the bucket is opcrated.

Fig. 3 is u horizontal section through the shaft, sliowing the bucket in place.

Referring to the drawings, in which the some numerals of reference indicate like parts throughout, 1 and 2 are the front and rear wells of the shaft. in which a bucket 23 is adapted to travel. The side walls 4 and 5 of the shaft are provided each with u flanged guide 6 end 7. secured to the middle thereof and being continuous with the shaft. The bucket is secured pivotully u on u bail S at the ends thereof. one being s iown ut t), the other not being shown, but constructed in a runner similar to the one illustrnted. The bail is formed with a groove in each arm adapted to rcccivc the llunc'cd guides e and 7, uppeurs in Fig. 3. The buil is pivoted neur its lowcr sides on the bucket. so us to cuusc it to dump nutmnuticully whcncvcr the proper openin; in the shnl't is rcu hcd. .\t its upper side isuttuchcd :1 chain It). which is drawn around :1- pullcy at the bend ol' thc shall in u well-known manner which nccd not here be illustrated or dcscribcd. The guides and grooves hcrcinbcl'orc nicntioncd rcndcr thc ascent and dcsccnt ol' the buckct ertain and Fig. 2 is a perspective view of the bucket, showm; the rollers thereon ,wnrdly and inwardly.

l \YlHclH or rollers 13 and 14, inounted upon I the front and back of the bucket,rcs icctivcly.

The rollers rcndcr the hoisting ol" the bucket eusicr, and there ure preferably a plurnlity both at the front and back. The opening in the shaft is pret'erubly provided with rollcrs 14 to lucilitute the dumpinc movement of the bucket.

15 is the dumping-apron.

lhe stop 16 on the side oi thc bucket limits the swing thcrcof rcurwurdly and ussurcs against dumping on the wrong side ol tinshuft it' pcrchance there should be an opening therctl'n'ougln On the inside of the shaft opposite the dumping-opening therein is secured u dcllcctor or tipping device 17, which curves up- As the bucket hoisted the rollers 14 reach the deflector, uud as they puss along its face the bucket is til! cd and the dumping. is thereby rendered certain.

To prevent the bucket from turnin coniplctelyovcr, us would happen il'it were noistcd above the proper dumping position, l provide the chain 18, secured at one end to thc bail. id 19, and at the other end to the back side of the bucket, at- 20. The length of the chain is sullicient to permit the bucket to assume a horizontal position with respect to tho shaft.

As the bucket reaches its maximum dumping iosition its lower end just clears the point of the deflector extending farthest into the shaft. As the bucket is lowered the front end turns about the rollers on the shaft, and the lower end and rear side pass downwardly along the face of the dellector until the bucket has assumed its normal position on the bail, whcrcupon it readily descends.

If the motor should be bundled improperly and the bucket on account thercoflbe carried bcyond the point intended, it is :n-iintuincd in its horizontal position by the boil-pivot uniform with respect to the sides. nnd the 5 front and back of the shaft urc provided, prelund the chuin and will constantly be held in the propcr position to puss the dcilcctor upon descending with its lower cnd and to come propcrly into contact with the rollers. whereby the buckct is rightcd. This construction and urrungcmcnt of purts provides against accidents duc to :urclcss handling oi' the hoistin; nnn-hiin-ry. l obviutc thc probubilityol' Lhciroccurrence us l'urus possiblc by opt-ruling two buckcts simultuncously. thc

erably, with metallic strips (indicutt-d ut ll onc ascending at the time the other is deand 12) which provide bcnring-surluccs for sccnding, so that the lowered position oi the dumping at the proper moment certain. The

; other in order to effect in many dumping dumping is furt er aided by the rollers provided on the shaft at the dump-opening therein. The chain attached to the bail and bucket prevents excessive tipping, and by holding the'bucket in ahoriaontal position prevents any accident or injury to t e shaft as the bucket is begun to be lowered. There are no parts required to interlock with each the dumping, as is seen devices in use, which arrangement is very likely to result in injuryto the parts if the operator is-negligent in any degree, and withal the parts are simple in construction and operation and are not readily put out of order.
